Title: Improvements in or relating to warning signals for vehicles
IPC: B60Q1/44
Filed: 1928-03-12
Abstract: 287,062. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). March 12, 1927, [Convention date]. Road - - traffic signals on vehicles.-The brake-lever of a tram, &c. is provided with a trailing switch which keeps the circuit for the "stop" signals closed on passing from braking to zero position, but leaves it interrupted for the running position and also for the change from running to zero. The member e is connected to the brake handle a and is provided with a stop m. A link provided with a pivot o on the member e carries a contact q which moves over a contact arc r. This link is connected with the member e by a spring p. A part t prevents movement of the link carrying the contact q too far away from the part e. If the lever a is in the running position or be returned from this position to zero the contact q lies against the stop m and the lamp or other signal circuit is open. On the other hand, if the lever is moved to braking position the contact q is moved on to the arc r and the signal circuit is completed, and when the handle is returned to zero, the contact q engages a swell s on the arc and is held in contact until the further movement of the arm has tensioned the spring p sufficiently to pull the contact over the swell s. A moving contact operated by the hand brake is arranged to open and close a parallel circuit and operate the signals.
